This story takes place when Macaque and Mk first meet (S1 E9) Instead of just taking Monkey King's powers from Mk upfront Macaque decides to earn Mk's trust, so he stays his mentor instead of betraying him. Mk grew to trust Macaque, so he decided to bring him to Pigsy's Noodles, the rest is for you to find out!

During a battle, Macaque gets injured, the group does not yet trust Macaque and is still skeptical so they leave the monkey king to watch over him, not only to make sure he is well healed but also so he doesn't run off or do anything destructive. The healing process is slow and painful, it hurts to even use his power. He finds himself unable to even move from his bed some morning. On the verge of death, Sun Wukong is worried for his ex-best friend.
